Chiller Room Refrigerant Monitor. When designing or considering the installation of a vrf (variable refrigerant flow) system for a new building or a retrofit to an existing system, the ramifications of ashrae 15 can play a big part. 4) if possible, monitor the vent line of the chiller.

In a mechanical room with three or more chillers, use multiple monitors or a single monitor with a multipoint sampling system. This type of monitor is capable of sensing multiple refrigerant gases using multiple sensing points. Usually it's the second level that you lock the chiller out on.
This Type Of Monitor Is Capable Of Sensing Multiple Refrigerant Gases Using Multiple Sensing Points.
Chiller room applications are the most common requirement for a refrigerant monitor. This includes, but is not limited to, central utility plants, boiler and chiller rooms, mechanical and electrical rooms, fuel rooms, as well as metering and communications closets. Areas such as central utility plants, boiler and chiller rooms, mechanical and electrical rooms, and fuel rooms house myriad process cooling and heating equipment as well as systems for comfort heating, ventilation and air conditioning equipment and systems.
In Most Cases, The Alarm Level Required Is 1000 Parts Per Million (Ppm).
Usually it's the second level that you lock the chiller out on. Chlorofluorocarbons, commonly known as cfcs, which were formerly considered relatively safe, are now known to be a key contributor to the thinning of the ozone layer. In a mechanical room with three or more chillers, use multiple monitors or a single monitor with a multipoint sampling system.

Gas are tucked away to do their job cooling the establishment. Refrigerants can be toxic and in some cases flammable, and a cause concern for the health and safety of people. Locate the sensor where refrigerant is likely to
The Chillgard 5000 Refrigerant Leak Monitor Provides The Earliest Level Of Detection Of Costly Refrigerant Gas Leaks In Mechanical Equipment Rooms.
Chillers provide a continuous flow of coolant to the cold side of a process water system at a desired temperature of about 50°f (10°c). To keep your mechanical or chiller room below workplace exposure limits, you should be meeting ashrae standard 15 (in the u.s.) or csa standard b52 (in canada). Ashrae 15 limits the amount of refrigerant that can be considered safe in an enclosed environment.
Ashrae 15 Also Applies To Chiller.
(boy is that web site hard to find anything on!!) does anyone know where i can find this information to prove to my supervisor. I am trying to find any information about chiller room refrigerant monitors and if they are an epa requirement in a chiller room that also has boilers in them? This type of monitor is capable of sensing multiple refrigerant gases using multiple sensing points.
